The date [day,week,month,year] x1=d1=k1 is recurrence/repetition of the date [day,week,month,year] of the first event x2=d2, for the x3=k3'rd time, in system x4.
x1 (plural of ordered pairs) is an exhaustive set (possibly infinite) of inputs/outputs defining a unary function which yields result x3 when given input x2; x1(x2) = x3
Number suffix initiating a subordinate clause representing a predicate whose arity is the suffixed number; the lambda variables representing the predicate slots are bound from the fo'a-fo'u series in their dictionary ordering; the number of bound variables is the same as the predicate arity.
Default number radix modifier: changes the value of the default radix assumed for any numeral lacking an explicit radix within the following text, until another {ju'ai} appears.
Number suffix initiating a subordinate clause representing a predicate whose arity is the suffixed number; the lambda variables representing the predicate slots are bound from the ko'a-ko'u series in their dictionary ordering; the number of bound variables is the same as the predicate arity.
x1 is any child of the first child of the first child of ... the first child of x2, where the graph geodesic through the ancestorship-directed family tree from x1 to x2 is of length (x3) + 1 (li; x3 must be a nonnegative integer or positive infinity), and where "first" is according to (partial) ordering rule x4 (default: chronological order of birth per successive generation within the given lineage; other restrictions on legitimacy etc. may be specified here as well).
f1=c1 [value] is a/the median/quartile/decile/percentile/fraction-type of median with numerator f2, denominator f3 in property/amount c2 (ka/ni) among p1 (s) (ordered set) by standard c4.
almost all/almost every/almost everywhere (technical sense): there is a non-universal conull subset (the complementary (sub)set of which is non-empty but of measure 0, where complement is taken with respect/relative to the universal set) of such things that are satisfactory.
